CX Auto-Calibrate Crosstalk 0x43 0x58…
Perform Crosstalk Calibration on tinyLiDAR. This correction factor is typically
not used as it is meant to try and correct for crosstalk from thin cover
windows placed in front of the sensor. The tinyLiDAR
module does not ship
with a cover window hence it does not require crosstalk correction by
default.
Before using this calibration command, please set tinyLiDAR to
Continuous,
High Accuracy
mode by issuing the commands “MC” and “PH”.
ST recommends to use a distance of 400mm to a gray (17% reflectivity)
target. Therefore, place a gray target 400mm away from tinyLiDAR
before
running this calibration.
Must specify calibration distance in mm.
The crosstalk factor will be placed in non-volatile memory and used for all
subsequent operations. This calibration takes about 10seconds to run and
the blue LED will flash slowly during the calibration. You can clear this
calibration out by running the “RESET” command.
Before using this calibration command, please set tinyLiDAR to
High
Accuracy
,
Continuous
mode by issuing the commands “PH” and “MC”.
